On the absence of ghosts in quadratic bigravity
Ioannis D. Gialamas, Kyriakos Tamvakis
An extension of the bimetric theory of gravity is considered that includes quadratic Ricci curvature terms associated with each metric. The issue of the Boulware-Deser ghost is ana…

Bimetric Starobinsky model
Ioannis D. Gialamas, Kyriakos Tamvakis
The bimetric theory of gravity is an extension of general relativity that describes a massive spin- particle in addition to the standard massless graviton. The theory is based o…

Bimetric-Affine Quadratic Gravity
Ioannis D. Gialamas, Kyriakos Tamvakis
Bimetric gravity, is a theory of gravity that posits the existence of two interacting and dynamical metric tensors. The spectrum of bimetric gravity consists of a massless and a ma…
